ok i know ill end up having to add more at some point, but at 2k rms i feel i wont need to unless i wanna sit and listen to my stereo. I have a 145 amp alt and 2/0 gauge through out and big three. I had a 1k setup and wasnt bad with voltage drop at all, well i went and got something a little extreme and have been keeping the gain cracked and watching Voltage meter closley.

What is a good but cheap batt? Or anyone got a good discount anywhere?
